If you have access to the Internet, you can get the latest distribution version of GNU Emacs by anonymous FTP; see https://org/software/emacs on our website for more information.
When you start Emacs, there is normally only one window in the frame.
However, you can subdivide this window horizontally or vertically to create multiple windows, each of which can independently display a buffer (see Windows). On a graphical display, the selected window shows a more prominent cursor (usually solid and blinking); other windows show a less prominent cursor (usually a hollow box).
to mean a graphical window or terminal screen occupied by Emacs.
The homepage for GNU Emacs is at https://org/software/emacs/. You can also purchase a printed copy from the FSF store.
For information on extending Emacs, see Emacs Lisp.
Emacs behaves very similarly on both kinds of frames. Henceforth in this manual, we will use the word “window” in this sense.
It normally starts out with just one frame, but you can create additional frames if you wish (see Frames). Graphical display systems commonly use the word “window” with a different meaning; but, as stated above, we refer to those graphical windows as “frames”. This displays various information about what is going on in the buffer, such as whether there are unsaved changes, the editing modes that are in use, the current line number, and so forth.
